进口先导式减压阀

进口先导式减压阀—德国沃德（WODE）集导阀和主阀于一体，导阀的设计与直接作用式减压阀类似,是一种高性能、外部取压、大流量的减压阀，无论上游压力的变化或下游负荷的波动，德国沃德（WODE）减压阀均能实现稳定的压力控制。Pilot type valve set the pilot valve and the main valve, similar to the design of the pilot valve direct acting pressure reducing valve is a high performance, external to take pressure, large traffic pressure reducing valve, regardless of upstream pressure changes ordownstream load fluctuations, pressure reducing valve can achieve stable pressure control进口先导式减压阀导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能，该产品主要用于蒸汽管路，起减压稳压作用。
